How can you say White people created racism when...?

The Egyptians had Jewish slaves. There are many other examples. A Racist is a person with a prejudiced belief that one race is superior to others. Is this not a clear example (BTW The Egyptians did view Jewish people as a race or should i say they viewed them as an inferior race). Also Couldn't you be a regular non-white villager and think 'I am better than them because of the country/tribe/family I'm from'. Of course. This stuff can't be tracked. You can't know that it was created by caucasians. I understand it might make sense but when you think about it; Isn't it ignorant to think such a thing? This question is to the people that believe that white people created racism so if you don't then you shouldn't be offended.
